Carlos Sierra is joining Enkitec soon

In a few days I will be joining Enkitec. Sure I will miss Oracle after 17 good years there. I made some really good friends and I learned a lot. I had the opportunity to build tools I thought were needed by the Oracle community, and I am glad they are been deployed all over the world. I am also pleased to know all these tools will continue helping our SQL Tuning community with no disruption.

A question I am often asked is: WHY Enkitec? I could elaborate on an answer but to keep it short, I would simply say “because I like the idea of contributing to an expanding team of outstanding professionals in the Oracle space“. I also value the close relationship between Enkitec and Oracle. I see this as a win-win.

At Enkitec I will be doing a lot of stuff. My main focus at the beginning will be database performance in general and SQL Tuning in particular. I foresee the possibility to open some SQL Tuning hands-on workshops using SQLTXPLAIN, SQLHC and some other cool tools and techniques. I also expect some additional duties and new areas of expertise to develop, which I embrace as new challenges and opportunities.

Overall, I feel very excited and ready to start walking this new career path. What can I say… Just when I though life was good it simply got better!

Congratulations Carlos. Looking for a quick help here. We have a materialized view in EBS prod. This materialized views are having partitions. One day it uses FULL TABLESCAN and other day it uses LOCAL INDEX ROWID, with usage of LOCAL INDEX ROWID the time consumed to execution is less compared with FULL TABLESCAN usage. Why does the optimizer behaves this way, is this known behavior? As far as database there are not init.ora parameter changes, except regular stats are collected. Help us an insight on this?

Congratulations. I hope all goes very well for you in your new job. The last time I heard from you, you had asked about our mutual friend, Mr. Rey. He is doing quite well. Send me an e-mail and I can fill you in on his latest projects. Best of luck at Enkitec.
